That is about as good as you can get. The rifle will recoil very little, shoots great with factory ammo and kills way beyond what its ballistics say that it should. Buy Hornady factory ammo and go hunt. Get him shooting out to 300 yards, just to be sure that he can score. That cartridge in whatever rifle you choose, will serve him well for as long as he wants.
Put a decent scope on it. Optics are more important than the rifle, usually.
